How to Use Mains PYQs Topic Wise

Start with the microthemes. Open a topic and read its microtheme list. The ones with the most questions are the ideas UPSC returns to.
Read the demand words. Note how questions begin: discuss, examine, critically analyse, comment. Each asks for a different answer structure.
Write by marks. A 10-mark question needs a tight answer of about 150 words, and a 15-mark question about 250 words.
Cover all years of a microtheme. Write the oldest and the latest question on the same microtheme, and see how the angle changed.
Revise and rewrite. Revise the topic from the notes, and write the same question again after a week.

For the method in full, read the Mains answer writing strategy. The official papers are on our UPSC PYQs page.
